Has anyone looked at possible mainboard or mainboard+logic board swaps to convert a D-series to E-series plasma? It looks like most of the differences between the 2 are processor upgrades and the addition of an "upgrade module" possibility. If the panel driver boards are the same maybe this is possible.

PSxxD4x0 to PSxxE4x0 is impossible because of the differences between panels.
D series have 1365x768 panels and E series have 1024x768 ones. I even tried to change the resolution setting jumper on the mainboard ( XGA / WXGA ) but no joy.
Plus there are no efficient setting in the service menu
